Jarrot Mansion

The Jarrot Mansion is located in Cahokia Illinois in St. Clair County. The Mansion is an Illinois State Historic Site and is a National Historic Landmark. Built in 1807 out of brick, it is one of the oldest masonry buildings in Illinois and is unique in that it is built in the American Federal architectural style rather than the French Colonial style found throughout the area. It was built as the home of Nicholas Jarrot, a French entrepreneur and land speculator, who helped Lewis and Clark by serving as an interpreter and who also owned the land where the winter camp of the Corps of Discovery, Camp River Dubois, was located in 1803.
